For the navigation view boatspeed comes with several enhancements:
You may now search for towns and regions by name, thanks to the Nominatim search service by open street map (c). Just enter a word and boatspeed tries to find a location for it. The service only works when you're online.
Of cause it's still possible to enter geocoordinates, with it a bunch of new formates are now understood. For example you may simply enter s.th. like 53.1 13.4. If a location is found, the map scrolls to it, but it is no longer added automatically to your route.
You may now share the position of a marker by long pressing the infowindow. Like before you may still share any position at the map by long pressing on it.
We have a bugfix for the night mode: All icons should now also be red - at least at most of the newer devices ;-)
The wind angel is now provided in 5 degrees steps insead of 10 degrees before.
Sailing comes with a new display, the depth which is you angel to the wind. So for now we have: heeling, vmg (velocity made good), heading, depth and your speed. All values are shown as provided by the sensors of your phone.
